    Well not much accomplished today, made a 2" block with a 1/2" tongue that i'll stick in the reciever hitch on the truck. Figure i'll jack up the rear to see if/when it snaps off. Then slice open the 2" block to have a peek inside (towards the end of wk though).

I have to have it done before noon so, and i had to modify the box a little, jeez she owes me bigtime...here's one pic- Click image for larger version.

    Todays project- kinda would like a "sand rammer" but not going to spend the $ on a new one (500-700) rebuilt ones go for around 200.00
    Well if it fails i learned that yamabond "5" works great to coat clay parts, makes a nice hard shell!!! Click image for larger version.

ID:	246760 edit- i had the kids play around w/it tonight and it hasn't self destructed yet.......

    Think i'll try a trizinger gas cap next, i've got the core setting up but not sure if my core sand is fine enough.Click image for larger version.

ID:	246776 3-days later-sand core failed...(need different sand)

    So i figured i'd make a mold of a stock tri-zinger cap, went to make some wax patterns(copies)- the top part of the cap is way too thin the wax won't even fill that area so molten alum wont either. Other than that the part came out great. Hmmm well i'm going to put that aside for now. Well maybe one more try.

    86/87 200x heat shield
    --edit--
    Here's as far as (i'm) going with it (had it mounted- good fit) my son claimed it for his bike, but he wants to take it to school and use the shop buffing wheel to shine it up more.
    I'll take it off his bike in the future to make more if needed or wanted, just have to run it for a bit so theres no issues.
    I'm pretty sure the header temp is 300-500 (guess?) if it reached melting point (1350ish) i've got other issues!!!
    I looked around, theres a few older motorcycles that use a cast alum heat shield. This one is about 4mm thick so it is strong. Click image for larger version.

    Very cool. Back in the late 70's and early 80's in my high school metal shop class, I sand cast a pair of aluminum DeHandler shorty brake and clutch levers for my IT175 using Red Rider's plastic levers for the mold. From what I recall they came out pretty nice and worked great. I also have a brass Moto-X Fox belt buckle somewhere at home that I cast from a friend's real Fox buckle. Good times, "back in the day".

    I'm really liking this hobby. Went to my son's school open house last week, hung out with his metal shop teacher most of the time/he found out through (AJ) that i was doing this and he had lots of questions about it and wanted to maybe start doing it at home "the school would not allow a furnace in the shop" He has found some small foundry stuff around the shop so someone has done it there in the past.
    Find myself looking around the house for things to make just for the hell of it, and to learn more. I have to get back to my original projects though.
    I have to cast my kids hands this sunday/should be interesting...

    I actually have some red brass on order so i can try it out, i figure whats another 400 degrees.......(over alum)

    The only issue i'm having is i still have my 80's hair (not short) every once in a while i can smell hair burning, i guess its time for a haircut. My forhead has gotten bigger though over the yrs.

    Cool! I haven't done any sand casting since high school. Back in the day they would actually teach you how to work with your hands.

    We ended up taking our son out of public school "he hated school, c student if he was lucky, same public school said he was a "slow learner" was in a special program they said that he needed. So we had our own specialist test him, the woman said that school was just using him for a # for state aide "they get extra funding from state for so many kids"
    Well very soon after we pulled him out.
    Now at a tech school- he's an honor roll student "top of his class" loves school now!!!
    Ok a little off topic but just wanted to point out that this new school teaches you to use your hands and actually learn more than what the state/gov "says to learn"
    Ok enough rambling- just a very proud dad here.

    Other son wants to be indiana jones or chef ramsey and will be going go a tech school as well....
    Have a great wk-end

Hell, If you could cast a "back half" of the Z cover and then weld the complex part of the OEM case to it in a little hold down fixture, that would probably work suprisingly well. Band saw OEM cases right infront of where the clutch housing area is, and weld it back to a reinforced area in the back. The fronts never break, its always the back around the kicker shafts. I'd be down to try that.
    I showed one of our casting suppliers a photo of a clutch cover and asked him for a quote last week.

    He said it would need to be injection cast and he could do the due for about $8,000 but that it wouldn't be worth running less than 10,000 pieces at a time.

    I didn't bother to ask what each part machined would cost, but I would guess they would be well under $50 bucks. So if anyone wants to invest $60,000 into Tri Z clutch covers let me know and I'll be happy to set you up. Myself, I think I'd try to carve one out of wood before investing in 10,000 pieces.
