I'm still awaiting my new tools. Fully excited to get going on this project to tackle this new challenge. I plan to share my experiences here. So far this is my plan.

Tools:
1) I'll be using the standard tools recommended in the MGB videos to complete the frame. Click on more under the video at Odysee to see the list of tools. Here's a post of the tools I suggest to get started if you are new to building.

2) The resource center has tools for new bridge frame suggested by the community and MGB. Tools will be added/deleted as the community works together as a team to brain storm best practices to get a FTQ build.

3) New tools I'm going to try:
Micro Sander- This is a knock of of the Micro Mark power sander...cuz Im a miser :LOL: too cheap to spend the money on M.Mark. Takes forever to get to USA from chiiiiina

Electric wood carving chisel - another piece of cheap china junk. I returned the 1st one it was bound/frozen and wouldn't work. Getting another today. Only good thing I have to say about this tool is it's a one day ship. Hoping this next one works. Does not work with the Dremel as the fitting is too large. Chuck it up in a drill.

This chisel tool oscillates. Im hoping the vibration will cut through the polymer. There are 2 flat blades the small one fits nicely in the pockets the large at the rear rail area.

Ill post up more as I get on this. 🎉

OK here's the chisel. It didn't work much better than the 1st one. Took em both apart swapped parts and have this one working now. There's a cam inside that converts spinning motion to oscillation.

This drill works ok but will try an electric harbor freight with higher torque to see if it's better. So far.., using this drill to power this chisel, its slow going. Hope the other drill works better.

Edit- don’t recommend this equipment for the frame. Ryobi power carver (scroll down the thread for a link) is better for detailed cutting and ease of use.

Yep MGBs snips and the diamond bits are looking better every day. I’ll give er another try with a better drill motor and maybe cobble up an exato blade on there also.
I’m surely not spending money for any micro surgery bone cutting tools.

WTF man? Those two videos side-by-side are fucking with my head. 😬 Looks like the audio is coming from George! 🔨 I thought Michele dubbed in some jack hammer sounds to be funny, but that's what the sucker sounds like.

I just clipped most of the material out with model snipers. Them shave most of the remainder of the material out with sharp hobby knife.

😂 it’s not helping that the frame isn’t secured in a vice. It’s hitting the counter as well. But yep it’s does have a jackhammer sound 😁

I don't think higher torque will help much, higher RPM maybe? I doubt this 'tool' has enough power or rigidity to cut deeply into the polymer, but it might work okay if you notched-out small "V" shaped wedges to help keep the blade from getting pinched and stuck in place when it cuts-in that deeply.

I would hazard a guess too that it might attach to a "WEN" brand Dremel-type tool. I got one a while back, it has plenty of power and worked fine except for the on/off rocker switch, which I have had to rebuild twice now (but plugging it into a switched surge-protector power-strip or a foot-operated plug-in switch would cure it too). The WEN uses a larger screw-on end, like for use with flex-shafts, than the Dremels do, so it doesn't work with Dremel flex-shafts or the Dremel Work-Station. Colet insert and cap sizes are different on the WEN too, so the only thing interchangeable with a Dremel are the bits themselves, but if it can get enough power and RPMs into your "jack-hammer" to increase it's function, it may be worth trying it.

Let’s see a photo
Here are a few pics of the new frame I am working on. The trigger housing area still needs a lot of work. The front locking block were the trigger pin goes has been removed and need some minor finishing work but pretty much ready to go there minus the holes being drilled

What tool(s) did you use to remove the obstructions

Update on my progress
Ok the china junk has shown it’s colors. The key that operates the mechanical parts turning them is nearly worn to nothing after about 20 minutes of jack hammering the fins. It quit on me. So… that’s a definite no go. That cheapo $20 tool is on its way back. Can’t expect much for $20 I guess. However, I’m not giving up on this technique. What little bit I have done I’m fairly happy with.

This is a work in progress…it’s still pretty rough looking & can all be polished up. (NOTE: don’t go running over to Reddit to post my unfinished rat eaten work. 😂 You know who you cross poster are 😝) The flat carver did a pretty good job of removing the fins flush at the areas identified by the arrows. The tool heats up a tad due to friction So polymer is easily shaved. This pocket is small with the front wall angled, it’s pretty thin and easily damaged if not cautious.

Think I’ll use the MGBs recommended cutters to get most of the rest of the meat out. Then try out my new Ryobi carving tool👈(amazon link) I just got at Home Depot. I’ll update on this tool

Dang, looks like the "obstructions" go deep. As in all the way down where the 3mm trigger housing hole is located and not just obstructions on the top arch section.
Is that the case?

Hard to tell in the photo due to the blur.
Thanks for sharing the photos.

:ROFLMAO: -Yeah, no fair 'ratting' us out with work-in-progress pics!

No you're talking! Reasonable price, and Ryobi usually makes pretty good tools -I have a few of them myself. That carver is new to me though, looking forward to your review.

I used a pair of model snipers to do some and my Dremel to do some.

Yes they go all the way to the bottom. Sorry about the photo of the trigger housing is crappy.
