So it's been a while since I updated the build. Mainly due to other projects, helping family members, and working on my "other" girl
I do have a few updates so I'll share those and hopefully I'll get back to working on this. When I last left off I was just mounting all different pieces. Basically I wanted to get all holes and modifications made before painting. So continuing with that I drilled the hole for the ribbon cable:
Drilled a hole for the pot that holds the crank knob on, and then mounted both:
Then I was trying to figure out how I wanted to mount the split loom to the crank box. First I was thinking of drilling a hole large enough to insert the loom but I thought I might have issues with the fiberglass and I wasn't sure how thick the resulting fiberglass would be. So instead I thought I would mount a wooden dowel to act as a peg, and the split loom will slide over the top of it. This way I can just put epoxy glue and there will be a lot of surface area to hold the loom on. So keeping with the "everything can be unscrewed/removed if needed" theme I planned to drill a hole and just tap it. That didn't work so well because there wasn't enough fiberglass on the bottom side for threads to hold. Instead I just drilled a through hole (no threads):
And opened up an area on the inside so I could add a nut and epoxy the nut in place:
I then cut a dowel down and drilled a hole in the center for the bolt, and then countersunk the head of the bolt and mounted it:
Next I started drilling holes for the tubing that goes between the shell and the injectors. That's when a catastrophe occurred. Near as I can figure there was a bunch of air pockets in that section and as I drilled holes into the area it weakened and exploded:
Only thing to do was to glue and resin it back into place. Took about 30 minutes:
While I waited for that to dry I sanded the ribbon cable clamp to fit the shell a little nicer and mounted that:
Then I got excited thinking everything was drilled and ready for texturing and painting. I followed the texturing tutorial here:

First I taped the areas I didn't want texture and then applied a layer of wall texturing:
And then applied primer:
While I waited for that to dry I cleaned up the booster frame and sanded the backside to the booster tube. I also found a bunch of air bubbles on the back side. So I went ahead and filled them will filler:
Once the shell dried of the primer I realized I hadn't mounted the shell yet. Minor oversight
So I went about my "common sense" approach to mounting it which is essentially the same as this tutorial: http://www.gbfans.com/community/viewtop ... 42&t=11972
Basically just set the shell on the motherboard and centered where I thought it should go. Then marked on the motherboard where the outside and inside (where I could) of the shell sat. The hole where the n-filter goes came in handy for marking the inside of the shell. Then cut my brackets from angle aluminum on my horizontal bandsaw. Taped them to the motherboard where I thought they should fit. Put the shell back on and verified any adjustments needed. Then I drilled the holes through the angle brackets and motherboard. And used rivets to attach them to the motherboard. Next I looked at reference pictures to figure out how far up the holes on the shell should go. Marked and drilled those holes with the tap drill bit. Removed the shell and tapped the brackets. Then drilled the holes on the shell with a larger drill bit so the screws/bolts would go through and had a little room for play/adjustment. Then finally bolted the shell on. I didn't really take step by step photos simply because there is already a tutorial. If anyone needs clarification please feel free to ask and I'll be glad to step them through the process. Here are the photos I did take:
Now that I mounted the shell I went ahead and sprayed a couple coats of Krylon Satin Black paint on the shell:
After the shell dried I'm not sure I 100% love my texture job. When the shell was in a duller primer I really liked it. After the black was on which has a shine, it almost looks over textured to me. What do you guys think? If any of the experienced people could chime in and tell me if it looks OK, or if I put too much on, or if the spray was not fine enough? I had done a practice run on a foam board to see what it would look like, and I felt the very fine pattern would look good on the upper part of the shell, but I felt a little heavier pattern would look better on the cyclotron. Now I'm not so sure. Some areas actually got sprayed more than I wanted just because they became overspray of another area. I think I'll leave it for now and see how it sits with me when everything is put back together. If I still hate it when everything is finished I'll strip it down and re-texture. Any opinions (good or bad) would be appreciated.
Then I hung all the bolt on parts so I could spray those:
I had wiped all of them down with some acetone, blew them off with the air compressor, and waited for any residual acetone to dry before I started to spray the black. Unfortunately the first couple of parts I sprayed had a chemical reaction from something and either lifted or became extremely blotchy. Luckily I noticed on the first 2 parts and stopped before spraying everything. I decided to strip the paint I sprayed, cleaned them again, and then sprayed primer before the black. Spraying the primer first resulted in no problems at all. I'm not sure if this black has issues, or if there was still something on the parts I didn't get off the first time. Either way I figure having everything with primer and color won't hurt anything. The only reason I wasn't going to spray primer on the aluminum parts was for weathering and when the paint chips off there would be 1 less layer of paint before the aluminum. However I figure when they get chipped, they probably will go through both layers anyways so I'm not too heartbroken about having to spray everything with primer first.
So now I'll get on my soapbox and preach.
drjameshouse's tips for painting:
- Slow down and take your time. I know it's exciting getting to put color on the parts but your really need to slow down and make sure your prep is done well. I think this was partly the reason my black lifted. I wasn't rushing, but I certainly wasn't taking it slow, since I wanted to get color on so the parts would be dry the next day
- Spray several light coats and not heavy coats. If the first coat doesn't cover everywhere, it's okay. There were a few places that I accidentally got too heavy and in those places the paint either ran or got blotchy or funny. Just spray some nice light coats and the finish will turn out great. Too many new painters think the first coat has to cover completely or they just want to rush and spray 1 coat instead of several. Don't. You'll thank me later.
- Read the directions of the paint and make sure to recoat within the time frame specified. I've had issues in the past not following the time frames specified. Most people don't realize that a lot of paint needs to be recoated within 1 hour or they will have to wait 24 hours. Just trust me and follow the directions.
- Finally, paint in a well ventilated area. For obvious reasons, safety is important.
