I was setting up the second engine to catch it up with the first. Wouldn't you know it one gear missing hmmm. SO I decided to try and do a gear set up with a hob cutter. I've always single pointed my gears but thought I'd give it a try so here is a short video of it getting turned up.

   Too bad I didn't do it correctly was suppose to make 5 teeth I made 4. I think I can still get it to work. It is heat treated now and is a respectable 63Rc. When I get some time Ill give it a try.

  Well made it to the shop for some time today between yard work and other things I had to do. I did try out the new hob cutter and did video it.
 :doh:  :doh:  :Doh:
 I did show how to machine gear without a rotary table or index head. It's processing right now and I'll get it up loaded tonight. Take a look and see if the cutter worked or not when I get it up loaded.
  Until then catch ya later.

Thanks Joules!

Well I did get the video uploaded and I really am going to change the way I cut my gears. It will be using a hob cutter from now on it worked out so well. Anyway my next trip to the shop will be to set up the timing of the cam in the second Little Demon engine.

Here is a link to the video if you care to take a look. I attempt to show how to make a gear without a index head or a rotary.

Why not just mount the pointer (with a magnet) on the vice?

 Well I cut the head gaskets and upon looking to start assembling I noticed a boo boo , Oh crap the coolant passage and has an error. I ran into the counter bore for the head bolt for the passage that goes to the intake manifold.  Crap! and I didn't drill the hole for the passage in the face of the head. So now I need to come up with a repair plan. I'm thinking of reaming up the counter bore and pressing in a spacer to the bottom of the hole but first I need to take the counter bore a bit deeper to give it a sealing wall so it wont leak. Then maybe mill a passage in the face of the head to connect to the block coolant passage. Anyway I may do a video showing what I'm talking about here.

  Ok I think I have sorted out a solution for the error. I videoed it and now I will start the final clean up of parts and assembly. Once I get the heads installed I'll get the rockers and push rods done. So today will be a spend some time getting things laid out to start putting together.
Hopefully I won't find too many more boo boo's.

Well was lining things up to start assembly and while giving the block assembly a going over I slid the cam out and messed up the cam timing. So I get to set up and set it again.   :bang:  I'll try and get some time in on it tomorrow before turkey time  :beer:

I was going to maybe give it a try after I make up an mold for them. Not sure if the stuff will work or not.

Thanks Anthony
   I did find some specs and it says the stuff is good fro 0 degrees f to over 250. I think I will get some and do some tests with it to see if it will work for this.

Need plug wires set distributor and then a gas tank and we are getting close. 










I ordered some castable rubber while I wait for that I may start with the rockers and push rods on the second engine.

    Had a bit of an incident in the shop last Sunday. I was out in the morning and the shop heater was acting up. So I decided to change the thermocoupler. I was standing on a small step stool and it decided to skip out from under me tossing me to the floor. I landed flat on my back. Unfortunately in the landing zone there was 2 pieces of square tube! It felt like I broke my back took me some time to get my breath back. I ended up going to the doctor the next day x-rays nothing broken just bad bruises and a 2 inch gash on my right arm. I was put on 2 pain meds and a muscle relaxant. Man I could not move at all for the next 3 days! I feel much better today and am going to see if I can get out there and do a little work this afternoon.

Thanks Andrew!
  I've had my trouble with spinal injuries. About 20 years ago I had 3 disks bulge in my neck and I was paralyzed on my left side. They went in to cut the disk away from my spinal cord to try and get control back of y left side. I did get most movement back but still have little tremors sometime in my left arm. I have been pretty careful for the most part not to end up in that situation again.
  I was out in the shop but just felt not all there so I came back in and am going to sit back and vegetate again today. Maybe tomorrow.
Here is a pic from about 20 years ago after I got out of the hospital.

 Nope couldn't work today just a little too messed up from the meds and didn't want to mess anything up so I decided to upload a little vid. Maybe tomorrow but I kind of doubt I'll make it.

You take it easy George and don't rush things - sometimes enforced cogitation time can be beneficial  :clap:
